Issues with Ingredient Usage in Cream/Lotion Formulation (Emulsifiers, Powder)

Question

I am developing a cream/lotion formulation and have questions about the correct usage of certain ingredients.

  • In a formula with 33% oil, I used Satin Cream Maker (ID 247). Is this suitable for emulsifying such a high oil load?
  • In another formula with 25% oil, I used Satin Cream Maker (ID 247) at 1% and Oil-Fix™ (ID 1136). Are these ingredients used correctly? I also added Matte Silica (ID 518) in the oil phase initially. Is this the correct step?

Answer

Hello,

Based on the information previously provided by the staff, the ingredients you selected for your formula are compatible. However, some items might be used for the wrong purpose or incorrectly, as explained by the staff:

  • Satin Cream Maker (ID 247): In the first formula (33% oil), the staff indicated it cannot emulsify such a high oil load and recommended Milk Lotion Maker (ID 1040) instead, possibly keeping Satin Cream Maker at 1% for viscosity. In the second formula (25% oil), the staff mentioned that 1% Satin Cream Maker might not be sufficient for emulsification, recommending at least 1.5% and using ClayThick Ready (ID 1163) for stabilization.
  • Oil-Fix™ (ID 1136): In the second formula, the staff stated that the formula is oil-in-water (O/W), not water-in-oil (W/O). Therefore, Oil-Fix™, which is a W/O emulsifier, is not suitable for this formula. ClayThick Ready (ID 1163) was recommended instead to stabilize the O/W formula.
  • Matte Silica (ID 518): In both formulas, the staff advised adding Matte Silica in the final step after the cream texture is formed, not mixing it in the oil phase initially.

Therefore, the ingredients identified as being used for the wrong purpose/step are Satin Cream Maker (used at too low a concentration for the oil percentage), Oil-Fix™ (used for the wrong emulsion type), and Matte Silica (added at the incorrect step).
